Abstract

The present disclosure relates to a power connector. The power connector includes an insulating cage and a terminal. The insulating cage defines a terminal holding space therein and includes a retaining wall. The terminal is in the terminal holding space, and includes an inserting portion, a stopping portion and a connecting portion. The stopping portion is abutted against the retaining wall and includes a first horizontal portion and a second horizontal portion. The first horizontal portion includes a first front edge. The second horizontal portion includes a second front edge. A portion of the respective front ends of the first horizontal portion and the second horizontal portion is cut. Therefore, when the terminal is clamped, the first front edge and the second front edge do not protrude forward and outward, but are parallel to each other or extend rearwards. Thus the case where the stopping portion will be abutted against the retaining wall in a wrong position due to the protrusion can be avoided. Therefore, the disclosed terminal can be assembled in the correct position in the insulating cage.
